摘要
利用基于极限平衡法的箱筒型基础防波堤稳定性分析方法,分析了不同结构尺寸对这种结构稳定性的影响。结果表明基础筒高的变化对抗滑稳定性安全系数的影响最大;倾覆极限状态时和竖向承载力极限状态时转动点位置对应的无量纲量l/L分别在0.5和0.9附近。
The effects of different structure sizes on its stability were analyzed by using a limit equilibrium method. And it was obtained that the height of the bucket foundation had greatest impact on anti-sliding bearing capacity of the structure. The dimensionless quantity l/L for the position of the rotation point in anti-overturning and vertical bearing capacity limit states were 0.5 and 0.9,respectively.
